Question

Quizplus · Accepted Answer

Speciation and extinction are the two main mechanisms that change global species diversity. Speciation increases diversity by generating new species, while extinction decreases diversity by eliminating existing species. Emigration, immigration, and extirpation are all processes that involve movement of individuals between populations, but they do not necessarily affect global species diversity in the same way as speciation and extinction.
